Hello

How do I update oslcass without losing use and Items which of this file in the attachment do I need to choose while doing backup?


Thanks

This option exports database, you should then download/backup files as well

When I clicked the upgrade button this is the message I saw


Tools
Upgrade

Your Osclass installation can be auto-upgraded. Please, back up your database and the folder oc-content before attempting to upgrade your Osclass installation. You can also upgrade Osclass manually, more information in the Wiki
Checking for updates (Current version 380)

For osclass 3.9 and prior, you must download .zip of osclass, extract it to your installation and then simply upgrade in backoffice.

How do I upload the entire folder of oc-include and oc-admin
